摘要:
A silver halide photographic material comprising a support having thereon at least one silver halide emulsion layer containing at least 1.0 x 10⁻⁴ gram equivalent of an anionic surface active material as anion per gram of a hydrophilic dispersion medium in the emulsion layer, the material having dispersed in the emulsion layer a light-collecting dye that has an emission band overlapping at least partially with the optical absorption band of a spectral sensitizing dye on a silver halide grain present in the emulsion layer, the light-collecting dye having an emission quantum yield of at least 0.1 at a concentration of 10⁻⁴ mol/dm³ in dry gelatin at room temperature, with the proviso that the light-collecting dye and the spectral sensitizing dye may be the same compound.
